Step-by-step explanation:
Vertical Angles:
The angles opposite each other when two lines cross.
They are always equal.
∠ 2(3a-7)° and ∠ (5a-6)° are vertical angles.Hence are equal.
So on Substituting we get
![2(3a-7)\°=(5a-6)\°](https://tex.z-dn.net/?f=2%283a-7%29%5C%C2%B0%3D%285a-6%29%5C%C2%B0)
Applying distributive property we get
![2\times 3a-2\times 7=5a-6\\6a-14=5a-6\\6a-5a=14-6\\\\\therefore a=8](https://tex.z-dn.net/?f=2%5Ctimes%203a-2%5Ctimes%207%3D5a-6%5C%5C6a-14%3D5a-6%5C%5C6a-5a%3D14-6%5C%5C%5C%5C%5Ctherefore%20a%3D8)
The value of a is 8
The Correct option is A) 8
